- My,4 invention relates to wvorks'up'ports for shoeornamenting machinery; Aof the classes known in the trade as cut-out and' 'perforatiiig machines and thelike; andthe improvements' Which I contemplate relate particularly tothe Work supporting, Work cutting, an'djwork holding devices lassociated With the -above noted class ofshoe ornamenting'machines.

lt is anobjec't of my invention to provide 10: quickly 'interchangeable dies for such machines'which are detachably mount/eden a supporting plate'. It isf'also an'object of invention to"` provide quickly`- detachable t gauging and clamping devices associated i5' with a Works'upporting plate.

y In my co-pending application, `Which-ma-u tured into PatentNoL 1,681,033, August 14th, 1928, Ihave disclosed. cutnit'A machine Which has become knoivnin the tradep'a's such,

"f5 and for purposes of illustration I have,"illus-` trated Aembodiments yof my inventionv associated with such: a machine.` iThis typefof machinel has assemblies of supports, cutting dies, and gauging and'vvorkliolding'devices which are movable from Work positioning to Work operating position.` i n Y A thas' been cus'tomaryypriorto my 'inven tion, to provide, i'or diierevnt types ofshoe's,`

Y Figure 2- is a plan'vievv of a supportingy plate Withthe dies for forming the cut-out Worki'n'an open Work patternshown detachably'mounted on theplate. i i Figure 3 'is aside elevation showing in combination `vvith asupporting plate a de-l tachabl'e mask', detachabledie plates, and a1 stripper' plate "for `el'evajtingi the Work from the-die plates after thec'utting out operation'. 70

VVVFigure l6is `a section through'a supporting plate showing onetype of clamping pin which may be usedfor detachably 'securing the dies or mask tothe support. I FigureffZf-is-'aplan view of a cutting die `80 detached'from" the supporting plate. n Figur'e'S is a plan view of a different type of cuttizng die assembly from that'shown in Figure .v H Figure V9 is a lateral section through thesup- 85 pprting plate with the mask removed from the 3136.1 p Generally indicated aty lis' the supporting plate, which, inther preferred type of cut-out machine to Which reference has been made, is 90 mounted so that clearance may be Thad for inserting a closed upper over orabout the Work support and cutting die assembly. The cutting diesl of which we have shown several ldiierent styles are indicatedin Figures 7 and 95.

8. The vdie 'assemblies are made of plates 2 having the`= cutting knives 3' Welded or other- Wise attached thereto, or beingfintejgrally formed therewith. 'I have shown theplates 2'Withv beveled dovetail portions 4, Whichslidi 100 after describedvin detail and illustrated in Fig. 6. The die plates have inclined lips 8 on their under surfaces which cause the spring pins to be depressed when the dies are slidably inserted in the slots 5. vThe die plates have apertures 9 in properalignment with the v spring pins, so that the inner end of the pins will interlock in the apertures when the die plates are in proper registry with the supporting plate. The dies maybe withdrawn by inserting a pin or pointed instrument through the upper end of the apertures 9 and depressing the spring pins 6 and at the same time sliding the dies outwardlyjin the dovetailed slots. f

Referring to Figure 2, it will be observed that there is a permanently attached central die portion 10 with two die plates 2 of the type shown in Figure 8. By withdrawing the removable die plates and allowing the central portion 10 Vto remain, a new patternfmay be cuty out by using different designed dies such as care shown in Figure 7, to form the main body of the design. Although I have shown different arrangements of cutting dies, it will beV within the scopey of my invention to provide dies of'similar shape but of different size. It is believedthat'the'economy of having the dies independent of the supporting plate will be quite obvious. A- skilled operator may change the dies from the supporting plate f more quickly than he could substitute a new assembly. f Y

In Figures 1, 3 and .5, I have shown .the supporting plate 1 with a work gauging and clamping plateattached thereto. The clampingplate'll with the cut out portion `11a by which the work is gauged and held down is attached to a hinge 12 which has a lower face with a dovetailed rib 13 in it. Y The rib 13 slidingly engages a longitudinally extending provided with a shoulderV 15s which functions Y to guide the-pin as it moves in the support 1.

Encircling the pin and having one end in engagement with the plate and the other'end engaging the shoulder 15s is a spring 20 which v tends to'normally move Ythe pin `out ofthe plate by its engagement with the shoulder. y

This outward movement is limited, however, by a head or other equivalent limiting means 21, which engages the supporting plate, as will be obvious. A locking portion 1571J eX- tends from the pin, beyond the shoulder 15s,

this portion being desirably reduced in diameter from the main diameter of the pin 15.

Figure' 3 shows the normal arrangement of the'complete assembly of supporting plate, detachable dieplates, and detachable clamping plate. This figure also shows a stripper plate 16 mountedy on pins 17 which are slidingly retained in apertures 18 in the supporting plate' 1 and tensioned to elevate the stripper plate from the supporting plate by the springs 19. -As shown'in Figure 3, when a stripper plate is used in the combination,it will ordinarily be so mounted that the die plates may be removed without making it necessary to remove the stripper plate also.

In the past die plates and clamping Vplates have been mounted on supporting plates with machine screws which could be removed. In a sense, therefore, the dies havebeen removably mounted. In the claims which follow, however, I employ the words quickly detachably mounted to signify a mounting which is readily accessible for detachment to the machine operator vwithout a long and tedious operation such as is required for removlng a set of machine screws. n Y
